Definition of gingivectomy
|
The excision of the soft tissue wall of a periodontal pocket
|
|
|
3 indications for gingivectomy?
|
1. Elimination of gingival enlargement
2. Elimination of suprabony pockets (psuedopockets) 3. Elimination of suprabony periodontal abscesses |
|
|
3 contraindications for gingivectomy?
|
1. Trx of pockets that extend beyond mucogingival jnx (mucogingival defect)
2. Trx of pockets associated w/significant furcation involvement 3. Trx of osseous defect that should be fixed w/a flap procedure |
|
|
3 ways you can perform a gingivectomy?
|
1. External beveled incision
2. Vaporize via electrosurgery 3. Vaporize via laser gingivectomy |
|
|
What instrument is used to make the external beveled incision?
|
Solt or Kirkland knives
|
|
|
What is used for interproximal incisions?
|
1. Buck knife
2. Orban Knife 3. #12B scalpel blade |
|
|
What can you use for gingivoplasty?
|
1. Perio knife
2. scalpel 3. Coarse diamond bur |
|
|
What is the difference b/t gingivectomy and gingivoplasty?
|
Gingivectomy excises the soft tissue wall of a perio pocket
Gingivoplasty reshapes gingiva to create physiologic gingival contours |
|
|
Is gingivoplasty usually used at sites that have perio pockets?
|
NO
|
|
|
Only indication for gingivoplasty?
|
Elimination of thick gingiva
|
|
|
T/F Healing after a gingivectomy is by primary intention.
|
False- by secondary
|
|
|
5 steps of healing after gingivectomy?
|
1. Clot formation
2. Clot replacement by granulation tissue 3. Surface epithelialization over 5-14 days 4. Complete epithelial repair after 4 weeks 5. Complete repair of connective tissue after 7 weeks |
|
|
What are the 4 perio problems generally trxed with perio surgery?
|
1. Unresolved deep pockets
2. Mucogingival defects 3. Inadequate clinical crown length 4. Unacceptable appearance (esthetics) |
|
|
3 reasons to perform initial perio therapy before surgical trx?
|
1. Provide access for root instrumentation
2. Provide gingival architecture that is compatible w/OH 3. Facilitate regeneration or reconstruction of perio tissues |
|
|
What is a resective procedure?
|
Involves excision of tissue
|
|
|
What are 2 examples of resective procedures?
|
1. Soft tissue: gingivectomy
2. Bone osseous resection (correct mild-moderate interdental bondy defects and calss I & II furcations |
|
|
What are regenerative procedures?
|
Involve replacement of perio tissues lost to disease
|
|
|
3 examples of regenerative procedures?
|
1. Root surface conditioning (use citric acid or tetracycline)
2. Bone grafting 3. Guided tissue regeneration |
|
|
What are mucogingival surgery procedures used for?
|
1. To widen the zone of attached gingiva and
2. to correct gingival recission for cosmentic purposes |
|
|
3 types of mucogingival surgery procedures?
|
1. Free gingival fraft
2. Subepithelial CT graft 3. Pedicle graft |
|
|
2 types of preprosthetic surgery procedures?
|
1. Crown lengthening
2. Ridge augmentation (for repairing localized alveolar ridge deformities) |
